step S7: after the ice crushing removal operation is completed, each hydraulic oil cylinder and each motor are started, each operation mechanism is recovered to a state before the operation, then the folding hydraulic oil cylinder is started, the telescopic folding rod and the folding rod are driven to retract, the vertical guide steel frame is driven to rotate to a horizontal position, and the horizontal folding recovery of the vertical guide steel frame is realized.
